ELECTROLUMINESCENT MATERIAL CONTAINING ORGANIC LUMINESCENT SUBSTANCE Russian patent published in 2007 - IPC C09K11/06 C07F3/06 C07D215/24

Abstract RU 2310676 C1

FIELD: luminescent substances, organic chemistry.

SUBSTANCE: invention relates to electroluminescent materials containing organic luminescent substance. Invention describes novel electroluminescent material consisting of injection layer, active luminescent layer based on chelate metal complex, hole-transporting layer and hole-injecting layer. Material comprises metal complexes based on sulfanyl derivatives of 8-aminoquinoline as a luminescent substance, in particular, zinc complexes of 8-(methylsulfanylamino)-quinoline and 8-(3,5-difluorophenylsulfanylamino)-quinoline. Material comprises a mixture of triphenylamine oligomers as a hole-transporting layer. Invention provides creature of electroluminescent material showing the enhanced moisture resistance, enhanced resistance to crystallization and enhanced thermal stability.

EFFECT: improved and valuable properties of material.
